ADJUSTABLE CURVED TYPE AND CYLINDEFI.

Specification of Letters Patent.

, Patented Feb. 6, 1906.

Application filed October 19, 1904. Serial No. 229,065 V To all whmn it may concern:

Be it known that I, HENRY'L. KOEHLER, a citizen of the United States, and a resident of Deer Park, in the county of Jefferson and State of Kentucky, have invented a new and useful Improvement in Adjustable Curved Type and Cylinder, of which the following is a specification.

My invention relates to a device by which detachable rigid type ma be rigidly arranged in.one or more lines on t is outer surface of a revoluble rigid cylinder in such manner that the face of the type in one direction shall form. part of a perfect cylinder and in such manner that one or more ty e may be added or is moved separately. attain these objects by thecontrivance illustrated in the accompany ing drawings, in which- Figure 1 is a perspective of the entire contrivance. Fig. 2 is a view ofthe strip below described. Fig. 3 is a section through the Fig. 4 is a section of the end piece and its inclosing flanges. Fig. 5 is a section of the groove and mortise.

The same letters represent the same parts in the various drawings.

A is a revoluble rigid cylinder encircled by oovesB B B. These grooves widen inward, orming the mortises G (J C. D D are strips or guard-bars, having loosely attached to them dovetails E. These dovetails fit loosely into the 'mortises. F F are countersunk screws which ass through the strips and the dovetails an by which said. stri s can be firmly fastened to the cylinder. '1 is is done by turning the screws until they meet resistance from the. cylinder. The dovetails are thus forced upward against the sides of the mortises and are firmly held and the strips as well. At one place on the cylinder G G G the 'rooves extend at the circumference to the Full width of the mortises, thus permitting the entrance of the dovetails into the grooves and mortiscs, and thus the strips are permitted to slide freely but securely around the cylinder, exceptwhen screwed fast. 1

H is the type, made preferably of metal, having a raised letter or other figure u )Ol'l its face, both type and figure hein curve circularly from top to bottom of the face of the t pe Its innersuri'iu'c curves similarly with the cylinder, against which it fits, and has at the top and bottom llungos I l, which lit loosely between the cylimlcr,mnl [hinges K K on the strips. There is no rim or flange around the ends of the cylinder, and the type may ordinarily he slid onto and from the cyl inder between the strips. When it is desired to fix the type in their places, the flanged end pieces 0 are slid against them between the strips and are secured by the screws P P, a'ct- .ing in the manner explained in the case of the screws F F.

i m n represent mechanism for using the c *linder in connection with a printing-ma 0 me.

My contrivance operates as follows: The dovetails on the strips are first inserted through the enlargements G into the inortises, so that the strips may be freely slid around on the cylinder. I then arran e a line of type in their order, placing t eir flanges beneath the flange of a stri which-is screwed fast to the cylinder. I t ien bring around another stri againstthe other end of the line of-type, so that its flange ovcrla s the flange of this other end, or instead of a 1 this I fasten the strips at the required distance apart and slide the type between in their proper order. then )roceed to slide in up a 'ainst each end of the line on end piece, which is fixed in place by its screw, above fully described. In the same manner various lines of type may be firmly adjusted at different arts of the cylinder. ny line or part of 9. inc of tvpe may be removed by on screwing an end piece and simply sliding them out between the strips.

Instead of having flan es on the ty 0 and overhanging flanges on t e strips, as \eretofore shown, I sometimes substitute beveled edges on the type or plate-types and corresponding bevels on the strips, adapted to hold t e typeor plates down, and similn'rlv in using type fitting in the mortiscs on the plates the edges of the type may be beveled and the interior of the mortise properly arranged for their reception. 1, consider this substitution, however, as a more mechanical change and not as one affecting the principle or nature of the contrivanoe.

I have thus set forthvarious minor points and conveniences of my comic. shoe; but its main merit consists in provid in a means for holding rigid typejn true 0 lin rical form on the outer surface of J rigi cylinder and for inserting or remaining at pleasure one or more lines or parts'of lines.

Having now fully described my contriv- ICC mice, what I claim as my invention, and desire to seeure by Letters lntent, ls
